Error compiling QtGstreamer for Windows XP with VS2008

[Karl Phillip]

 Hi all,

I'm trying to compile QtGstreamer using VS2008. I already managed to
compile Gstreamer, and have everything else is properly installed
(ossbuild, qt, boost, byson/flexm automoc, cmake).

I've made a few tests with gst-launch and also succeeded writing a "Hello
World" Gstreamer to play audio/videos and everything seems fine.

I'm following the instructions from
http://gstreamer.freedesktop.org/wiki/QtGStreamer/BuildingOnWindows

Looking at the instructions at section "Building QtGStreamer", after
setting the PATH cmake is being configured with:

cmake -G "Visual Studio 9 2008"
-DCMAKE_INSTALL_PREFIX="C:\qt-gstreamer\install" ^
-DBOOST_ROOT="C:\boost_1_45_0"
-DCMAKE_INCLUDE_PATH="C:\ossbuild\Shared\MSVC\Include;C:\ossbuild\Shared\Build\Windows\Win32\include\libxml2"
^
-DCMAKE_PREFIX_PATH="C:\ossbuild\Build\Windows\Win32\Release;C:\ossbuild\Shared\Build\Windows\Win32;C:\automoc\install"
..

This outputs:

I have to use Boost 1.45.0 as suggested by the site because 1.48.0 gave me
compiling erros inside Boost. Anyway, if you notice the variable
CMAKE_INCLUDE_PATH you'll see that the include path for libxml2 is also
being added. That's because I'm trying to fix the errors which are all
related to:

9>C:\ossbuild\Build\Windows\Win32\Release\include\gstreamer-0.10\gst/gstconfig.h(131)
: fatal error C1083: Cannot open include file: 'libxml/parser.h': No such
file or directory


Now, I know for sure the path
"C:\ossbuild\Shared\Build\Windows\Win32\include\libxml2\libxml\parser.h" is
valid.

I'm not sure how to fix this problem. Hopefully someone can shed a light on
this.

Thanks,
